Detailed Description

This is an internal function and should not be used directly

This is a partial specialization of the remote_call_issue classes described in function_call_issue.hpp and request_issue.hpp to handle the portable calls A portable call permits function calls across different binaries, but required registration.

Portable Call Formats
=====================
The format of a "portable call" packet is in the form of an archive and is as follows

• size_t(NULL) -- NULL. Corresponds to the dispatch_type* in the native call
• std::string -- name of the function to call
• char(0) -- flag that this is a call
• fn::arg1_type -- target function's 1st argument
• fn::arg2_type -- target function's 2nd argument
• ...
• fn::argN_type -- target function's Nth argument

Unlike the native call, argument casting is performed by the caller. The caller is required to know the type of the function (At least through a function prototype)

---------
The format of a "portable request" packet is in the form of an archive and is as follows

• size_t(NULL) -- NULL. Corresponds to the dispatch_type* in the native call
• std::string -- name of the function to call
• char(1) -- flag that this is a request
• fn::arg1_type -- target function's 1st argument
• fn::arg2_type -- target function's 2nd argument
• ...
• fn::argN_type -- target function's Nth argument

Unlike the native call, argument casting is performed by the caller. The caller is required to know the type of the function (At least through a function prototype) At the end of the request, the dispatch will perform a fast call to the reply_increment_counter on the source machine passing the ID as an argument. The return data is passed using the actual result type of the function.
